Holographic Projection - For past 10 years keyboards and touchscreen where used for input in smartphones. Evolution from keyboard to touchscreen made a remarkable changes to the mobile phone. So now what is next? Is it fully voice aided mobile? No, currently there is project regarding Holographic Projection. It looks like exactly the below given image.
Virtual holographic projection imaging technique make use of interference and diffraction theory. It record and reproduce objects in real three-dimensional image. Before it was said that this input method will be available for Google Glass. It projects a virtual keyboard in the hands and will be user for human-computer interaction. If Holographic Projection is implemented successfully many touch screen such as one we seen in “Iron Man” movie can be implemented.
